C1282 GMC Code - Yaw Rate Sensor Bias Circuit Malfunction
Quick Answer
The Vehicle Stability Enhancement System (VSES) is activated by the Electronic Brake Control Module (EBCM) calculating the desired yaw rate and comparing it to the actual yaw rate input. Common causes include Faulty Steering Wheel Position Sensor (SWPS), Faulty Yaw Rate Sensor, Faulty Electronic Brake Control Module (EBCM). Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C1282 GMC Description
The amount of differential braking applied to the left or right front wheel is based on both the yaw rate error and side slip rate error. The side slip rate error is a function of the lateral acceleration minus the product of the yaw rate and vehicle speed. The yaw rate error and side slip rate error are combined to produce the total delta velocity error. When the delta velocity error becomes too large and the VSES system activates, the drivers steering inputs combined with the differential braking will attempt to bring the delta velocity error toward zero.
The VSES activations generally occur during aggressive driving, in the turns or bumpy roads without much use of the accelerator pedal. When braking during VSES activation, the brake pedal will feel different than the ABS pedal pulsation. The brake pedal pulsates at a higher frequency during VSES activation.
What are the Possible Causes of the DTC C1282 GMC?
- Faulty Steering Wheel Position Sensor (SWPS)
- Faulty Yaw Rate Sensor
- Faulty Electronic Brake Control Module (EBCM)
- Yaw Rate Sensor harness is open or shorted
- Yaw Rate Sensor circuit poor electrical connection
